IMPROVED MODE 0F PROTECTING THE METALLIC SHEATHING 0F VESSELS.

Specification forming part of Letters Patent No. 346, dated August 8, 1837 To all whom it may concern:

Be it known that I, EDWARD M. ROBINSON, of New Bedford, in the county of Bristol and State of M assnchusetts, have discovered a new and useful improvement in the art of preserving copper or other metallic sheathing from corrosion and waste when applied to the sides and Ma ena vessels; and I do hereby declare t at e following is a full and exact description of my process.

Take of paint made by grinding pure verdigris in linseed-oil and diluted to a proper consistence to be applied to the sheets of metal, with a mixture of one gallon of linseed-oil and half a pint of a lacquer, prepared as follows, viz: by boiling together seven and a half gallons of linseed-oil, four pounds of shat- ,la-c, four pounds of jrenfigad, and four pounds oflihher gg until the s'h llac is dissolved. Apply this paint with a brush to both sides of the sheets of copper or other metal intended to be used, and when dry add one or more coats, as may be desired. If it is wished that the paint should dry very rapidly, a half a pint of spirits of turpentine may be added to every gallon of oil-used in diluting the paint. When the paint is perfectly dry and hard the sheets may be fastened upon the vessels bottom in the usual manner. This paintmay also be applied'to metallic sheathing after it has been placed upon the bottoms of vessels, and it may also be applied to but one side of the metal before being fastened upon the vessels bottom; but it is decidedly preferable to use it as first described.

What I claim as my discovery in the art ofprotecting the copper or other metallic sheathing of vessels from corrosion is that by the application of a coating of paint in which verdigris is'the principal ingredient to such mctallic sheathinginthc mannerabove described such protection will be effectually attained.

I do not claim to be the inventor or discoverer of the above-described paint, nor doI intend to limit myself to its application in the form prescribed, but to use verdigris mixed with oil or varnish in any of the modes in which a desirable paint is produced in which the main body consists of verdigris, limiting myself to its employment for the purpose of protecting the metallic sheathing of ships or vessels, such application being, as I firmly believe, new in the arts.

EDWARD M. ROBINSON.
